I know how hard that must have been for you. I'm sure you made the right decision and Jazzy will be happy as can be in her new home.
I am going through a similar situation right now. I kept my male puppy as a show prospect and he is absolutely perfect in every single way except one - cryptorchid. It is breaking my heart because I also love him so much. I have to make a decision very soon, but the thought of not keeping him is really, really tough.
